According to PopCrush.com, the couple will walk down the aisle in front of family and friends at a country club in Khalifa's hometown of Pittsburgh, Pennsylvania.

"When we do get married, we want to have babies and be able to have time to spend with each other," Rose previously gushed about Khalifa.

On Thursday, Rose posted a picture on her Instagram of her wedding dress being delivered in a box that red, "Fragile."

Rose, who previously dated Kanye West back in 2010, told Starmagazine that her relationship with the Yeezus rapper ended because of Kim Kardashian.

"Kim is one of the main reasons why me and Kanye are not together," Amber said at the time of the interview. "She's a homewrecker. They were both cheating. They were both cheating on me and Reggie Bush with each other."
